I could have sworn I read you teaching in some previous thread but mistaken. you seem to have unusually well organized thought process on techniques to be just doing it for fun. I too am a student of the game and bettering myself is one of the things I enjoy most. I also try to have an open mind and I don't care where an idea comes from. but not rejecting unfounded idea is not same as having an open mind.

Thank you for the kind words, borami. I enjoy reading your posts, and I think you have a pretty good insight into tennis. I do have a few points where I don't see eye-to-eye with Oscar, but he might just be right. The 2hbh is one example. I know he advocates an open stance, but I've had my best results with a closed or neutral stance, and I see pros using a closed stance whenever the opportunity affords. It's still a work in progress for me...
